Firestore-Listener-Flow

It is a library for simplifying Firestore listener callbacks to Kotlin flow and suspend function to easily manage and use callbacks.

Firebase callbacks like addSnapshotListener and addOnCompleteListener are simplified using Flows so you can easily write clean code.

Steps

1. Add the JitPack repository to your build file Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
	     ...
             maven { url 'https://jitpack.io' }
	}
}

2. Add the dependency

dependencies {
      implementation 'com.github.KaushalVasava:firestore-listener-flow:1.0'
}

Demo Example

You can use now toValueFlow instead of addOnSnapshotListener.

  val cartFlow: Flow<BaseState<Cart>> = 
        Firebase.firestore.collection("users").document(userId)
            .collection("cart").document(userId).toValueFlow<Cart>()
            .map { cart ->
                BaseState.Success(
                    Cart(
                        items = cart.items.entries.associate {
                            it.key to BaseState.Success(it.value)
                        },
                        cartId = cart.id,
                        addressId = cart.addressId
                    )
                )
          }
